Fixed In Version: sssd-1.5.1-35.el5
Doc Type: Bug Fix
Doc Text:
When the first DNS entry defined in the /etc/resolv.conf file was unreachable, SSSD failed to connect to any subsequent DNS server to resolve the SRV record. This caused SSSD to permanently operate in offline mode. This bug has been fixed and SSSD is now able to connect to an alternate server if the primary server is down.

Comment 2 Kaushik Banerjee 2011-05-27 10:34:49 UTC 
1. Tested with 2 unreachable nameservers at the beginning in resolv.conf.
2. Enable debug logs and restart SSSD.
3. Enumeration and auth works fine.
